I'm sure that Valleyfair can squeeze a coaster in the park that does not require moving the entire maintenance building. Plus, a B&M invert in Valleyfair isn't a matter of "where", it's more of a matter of "is it going to happen".
A great launch, a nice top hat with floater airtime, and overbanks that make a nice ending puts Xcelerator as my favorite coaster with such a short duration.
You can do a No CD crack to RCT2. I bought RCT2 on Amazon, so it has no CD and it's working completely fine, though it does require some trial and error when you're putting the crack into place.
Honestly, Knott's is a great place to have people get over their fear of roller coasters as they have 4 family coasters there.
If you aren't going to Knott's, then Ninja is a pretty good starter coaster for those who have a fear of coasters.
Great trip report.
When I visited the park last Sunday, I was impressed with what they did with the Mine Ride. It was a nice sight to see the Mine Ride's line go into the switchbacks (and with great operations, it only took 10 minutes of waiting).
